Specification of Letters Patent.

Patented July 3, 1906.

Application filed April 12, 1906- Serial No. 311,206.

To all whom it may concern:

Be it known that I, CHARLEsW. BORSDORF, a citizen of the United States, residing in Haledon, county of Passaic, State of New Jersey, have invented certain new and useful Improvements in Cue-Tips and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to letters of reference marked thereon, which form a part of this specification.

My invention relates to billiard-cues; and it consists in certain improvements therein having for their object to provide for attaching the cue-tip so that it will not become detached under ordinary wear and tear and yet may be readily removed, to be replaced by a new one, when it becomes flattened or otherwise worn. I accomplish this object without materially increasing the cost of manufacture and without imparting to the cue an appearance in any respect different from that of ordinary cues.

Referring to the accom anying drawings, wherein my invention is fully illustrated, Figure 1 shows the tip end of a billiard-cue constructed in accordance with my invention, the same 'being partly in section. Fig. 2 shows the tip end of the improved cue with the tip removed. Fig. 3 shows in section the base member of the tip, and Fig. 4 shows in side elevation the top member of the tip.

In the drawings, a, is the cue. Into the tip end thereof is driven or otherwise fixed a threaded stem or stud 1), arranged in the true axis of the cue. The tip 0 preferably comprises three partsto Wit, a base member d, a top member 6, and a threaded member f,

adapted to engage the stem or stud and so secure the tip to the cue. These parts are arranged and constructed substantially as follows: The member d has a hole 9 extending axially therethrough and a countersink h on its top surface. Into this countersink, which by preference is of non-circular shape, is fitted the member f, which may be an ordinary nut having a threaded bore & to engage With the stem or stud b. The top member e is of usual form, having a concave top surface and a flat bottom surface, the nut f being set in the countersink h. The top member is cemented onto the top surface of member (I. The tips are placed on the market with the nuts thus embedded in them. Thus constructed the cue-tip will remain properly affixed to the cue under the roughest handling until it becomes so flattened or otherwise worn as to require to be replaced by a new one.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

In a billiard-cue, the combination of the cue proper, a threaded stem forming an extension thereof, and a composite tip comprising two members cemented together and a nut interposed between, and embedded in one of, said members, said tip having a stemreceiving hole and the nut being screwed on said stem, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 7th day of April, 1906.
